A new kind of radar has been developed for spaceship travelers. A working laboratory model

of a new system of radar that makes use of a beam of light is said to be ten thousand times more accurate than the best comparable system of radar that used microwaves.

The model has shown that this radar system, known as laser-doppler radar, can measure with absolute precision speeds varying from spaceship orbital injection (进入) velocities (速度) of five miles per second down to virtual stops--speeds of less than one ten thousandth of an inch per second. According to the scientists who are developing this system, such fine measures of velocity are of prime importance in space missions. In a rendezvous (对接) between two spaceships, or in a landing approach by a vehicle onto an orbiting space station, a bump could rip open a ship's skin, or a nudge could knock the station out of its orbit.

The light-beam radar, which operates at a frequency of trillions (百万兆) of cycles per second, could easily detect and measure the movement of a vehicle edging up to a satellite space station. A control system using so precise a signal as this would allow a huge vehicle to dock at a space station as lightly as a feather.

Laser-doppler radar ______. ()

A．measures the movements of a spaceship by means of light beam

B．makes use of microwaves

C．makes use of sound waves

D．Both A and B

One of the industrial giants who changed American society was Henry Ford born on a farm in

Michigan in 1863, and he grew up to bring forth some of the most revolutionary improvements in automotive technology in the early 20th century. His outstanding mechanical ability led him to become interested in the new automobiles in the early 1900s. Though he did not invent the automobile, he improved upon everyone else's designs. He was a person who believed in inexpensive, efficient production, so he established standards for his plants and workers. He also standardized and produced many new auto parts for his Ford Motor Company cars. Then he studied the workers' problems and thousands of automobiles per year. In fact, his plants had produced 15 million Model TS by 1927. Ford's personality was not all thrift(节俭), efficiency and inventiveness, however. He was a man who was cold and who could not keep pace with the competition due to his own rigidity(严格). His company suffered because of his desire to maintain the existing state instead of meeting and beating the competition by changing his products. Finally, he saw that he must change or fail, therefore, he introduced a newtype engine and once again took over the automobile market. Ford left a legacy of millions of dollars, millions of jobs for American workers, and millions of satisfied customers.

Henry Ford changed the American society ______. ()

A．through great social revolution

B．through automotive technological revolution

C．through numerous mechanical inventions

D．through radical political reforms

Questionsare based on the following passage．Never before has so much money been made by a

Questionsare based on the following passage．

Never before has so much money been made by a single firm in such a short period of time．OnJanuary 27th Tim Cook， the boss of Apple， announced that it had made $18 billion in its latest financialquarter．Apple"s telephone-number-sized profit stemmed largely from sales of its hugely popular iPhone， which accounted for over two-thirds of its $ 74．6 billion revenue．Chief executives rarely admit to being shocked by their companies" performance， but Mr．Cook said it was "hard to comprehend" the extent of the interest in Apple"s products．He noted that， on average，34，000 iPhones were bought every hour of every day during the latest quarter．

Apple is the world"s largest company by market capitalisation （总值） as well as its most profitable．Strikingly， it has risen to greatness using a rather old-Fashioned business model: sellinghighly desirable objects at fat gross margins， which hit almost 40% in the latest quarter．The tech

industry has bred numerous software-based finns， such as Google and Facebook， that don"t have to worry about shifting goods around， yet they make much less than the Colossus of Cupertino．Amazon handles lots of physical goods， but loses money．

Another thing that sets Apple apart from the tech pack is its success in conquering China．Whilerivals have been frustrated there， Apple has just become the largest force in China"s smartphone market measured by units shipped， according to Canalys， a market-research firm．Any failure in China could hurt Apple．The company"s overall dependence on the iPhone is anotherrisk．But these are early days for the iPhone 6， Apple"s latest device， whose bigger screen takes the firminto the "phablet" （平板手机） category of larger phones that are wildly popular with customers．Some

iFans also point out that Apple"s share of the smartphone market is small compared with devices using Google"s Android operating system．So it has plenty of room to grow．Mr．Cook said this week that its much-anticipated smartwatch will go on sale in April．Tim Bajarin of Creative Strategies， a consulting ftrm， thinks Apple could sell 22m -24m in the first 12 months after

the launch， producing billions of dollars of new revenue．Sanford C．Bernstein， a research firm， reckons the watches will have a higher-than-average gross margin， which predicts good profits．Apple should be able to make more money from software and services， too．

A large part of Apple‘s fat profit comes from__________．查看材料

A.the sales of its smartwatch

B.the sales of its software

C.the sales of its service

D.the sales of its iPhone
